BOSTON - Major League Baseball announced late Friday night that Boston Red Sox third baseman Kevin Youkilis has been added the American League All-Star roster.

Youkilis replaces the Yankees' Alex Rodriguez, who asked out of the festivities due to a knee injury. Teammate Derek Jeter will also miss the game and was replaced by Detroit Tigers shortstop Jhonny Peralta.

“It was definitely a surprise yesterday, but it’s a great thing,” Youkliis said. “I’m excited to represent the American League and the Boston Red Sox. Hopefully we can come out on top in that game because it might mean a big thing for us down the road.”

It marks Youkilis’ third selection after also participating in the game in 2008 and ’09. He was hitting .275/.393/.491 with 12 homers and 59 RBIs entering Saturday.

His selection brings the Red Sox All-Star tally up to five with David Ortiz, Adrian Gonzalez, Jacoby Ellsbury and Josh Beckett accounting for the other four spots.

Beckett to get tested: Beckett, who suffered a “mildly” hyperextended left knee while throwing on a damp mound during the fifth inning of Friday’s game, played catch Saturday and will throw a side session Sunday.

Team medical staff will then reevaluate him and determine his status for the All-Star game.

“We don’t want to hold up the league, they got their hands full,” manager Terry Francona said. “If he’s OK, he’s OK. If he needs a couple off, we’ll do that also. Certainly respect the All-Star stuff, but we also have an obligation to our team.”

No word on Ortiz, Saltalamacchia: David Ortiz fully expects to hear from the league office for his part in Friday night’s bench-clearing brawl with the Batlimore Orioles, but no action has yet been taken.

In fact, the team doesn’t expect to hear anything for at least a week.

“I expect we won’t hear anything until after the All-Star break,” Francona said. “It’s a nice time for the league, they don’t want to be talking about what happened last night.”
